. IMPLEMENT QLEAN TEXTILES v Original Filed Nov. 2. 1931 Patented May 8, 1934 IMPLEMENT TO CLEAN TEXTILES Erich Heckert, Berlin, Germany, assignor to Hanns Renter, Berlin-Steglitz, Germany Application November 2, 1931, Serial No. 572,531. Renewed March 31, 1934. In Germany March 2 Claims. (Cl. 15-105) The present invention relates to brush like implements for cleaning textile materials and has for its object to provide a hand tool of moderate cost which is easy to handle and which may be used for very difficult cleaning purposes.

Another object is to provide an implement with advantages of a vacuum cleaner, that is, to collect the dust in the interior of the brush without spreading it around into the air.

The new form by which the above objects are accomplished comprises an oblong body which is provided with ribs on its underside; said ribs are made from non-conducting material, or at least the surface of them is made electrically nonconducting. Bristles are arranged incombination therewith, the bristles being preferably of such length, that ribs and bristles are of at least equal height. Through the combined action of the ribs and the bristles, mud and dust adhering I to the material, will be removed by the bristles and will be caught by the electrified ribs.

Other objects will be found set forth in the following description.

In the drawing:

Figure 1 is a perspective view of the combined implements.

Figure 2 is a plan view showing the bottom portion of the device.

Figure 3 is a sectional view taken on the line 33 of Figure 2.

The body consists of a back 1 made from wood or any suitable material, to the underside of which a plate 2 of hard rubber or other electrifiable material is fixed, which latter is provided with ribs 3 which are preferably arranged lengthwise upon its underside. In the back 1 as well as in plate 2 are cut slots in which a bru"h 5 with its bristles 4 is inserted. The two slots in both parts are superposed but they are of somewhat different width: the slot in the back 1 is made wider to hold the brush handle 5 while the slot in the rubber plate 2 is narrower so as to just allow the bristles to pass when the brush is inserted in the slots from the side. Advantageously the slot in the rubber plate 2 is even narrower than the brush part, whereby the whole brush is held by the friction of the bristles in this slot. The bristles are made so long, they will project slightly beyond the ribs, when the lower edge of the brush handle bears against the edge of the rubber plate 2. With this arrangement the bristles act effectively upon the material to be cleaned, dust and mud being loosened by the bristles and caught by the electrified ribs 3. When used as described, the handle of the brush may be lightly held down with one finger -of the hand in which the device is held. In order to remove dust without the combined brushing action, the finger may be removed from the back 5 of the brush, whereupon it will slide back due to the reaction against the material, so that the bristles will not act upon the fabric, sparing it in a high The ribs 3 will gather the dust on acdegree.

count of the electricity developed by friction.

The back 1 on the side opposite the brush 5 may be reduced in thickness, so that the brush may be used in constricted places.

ribs 3 where it has accumulated.

Details of the implement described may be changed within the scope of the invention hereinbefore set forth and hereinafter claimed.

I claim:

1. A cleaning device comprising stationary projections with recesses contiguous to said projections, a separate brush containing bristles, said bristles being adjacent said projections and of a length to at least be flush with the ends of the adjacent projections, said projections being of material which is electrified by friction, and receiving and retaining by electrical attraction dust and the like from the article over which the cleaning device is rubbed, said separate brush being detachable so as to be usable for cleaning said projections, said cleaning device having a slot for receiving said separate brush with the bristles projecting as aforesaid adjacent the ends of said projections.

2. A cleaning device comprising stationary projections with recesses contiguous to said projection, a separate brush containing bristles, said bristles being adjacent said projections and of a length to at least be flush with the ends of the adjacent projections, said projections being of material which is electrified by friction, and receiving and retaining by electrical attraction dust and the like from the article over which the cleaning device is rubbed, said separate brush being detachable so as to be'usable for cleaning said projections, said cleaning device having a slot for receiving said, separate brush with the bristles projecting as aforesaid adjacent the ends of the projections, said separate brush having a portion projecting above the back of the device by which the bristles may be pressed against the article being cleaned.
